+Horizontal alignment may be fine-tuned
+using a numeric value:
+
+@lilypond[quote,verbatim,relative=2]
+a1-\markup { \halign #-1 poco }
+e'
+a,-\markup { \halign #0 poco }
+e'
+a,-\markup { \halign #0.5 poco }
+e'
+a,-\markup { \halign #2 poco }
+@end lilypond
+
+@noindent
+Some objects may have alignment procedures of their own,
+and therefore are not affected by these commands. It is
+possible to move such markup objects as a whole, as shown
+for instance in @ref{Text marks}.
+
+@cindex text, vertical alignment
+@cindex vertical text alignment
+@funindex \raise
+@funindex \lower
+
+Vertical alignment is a bit more complex. As stated above,
+markup objects can be moved as a whole; however, it is also
+possible to move specific elements inside a markup block.
+In this case, the element to be moved needs to be preceded
+with an @emph{anchor point}, that can be another markup element
+or an invisible object. The following example demonstrates these
+two possibilities; the last markup in this example has no anchor
+point, and therefore is not moved.
+
+@lilypond[quote,verbatim,relative=1]
+d2^\markup {
+ Acte I
+ \raise #2 { Scène 1 }
+}
+a'
+g_\markup {
+ \null
+ \lower #4 \bold { Très modéré }
+}
+a
+d,^\markup {
+ \raise #4 \italic { Une forêt. }
+}
